Just curious. I think he meant CHOST sets just *default* so any user-set -march overrides that. But I wonder what happens to user-set -mtune then? Since AFAIK -march implies -mtune, will also the default -march override user-set -mtune? - -- Vlastimil Babka (Caster) Gentoo/Java -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGndsrtbrAj05h3oQRAp5hAJ4in2JnV637D7GyDMvG6hc8A8/n4QCeK9Eo IFUTZxAFqfSVx3Za64GQM0c= =6wSA -----END PGP SIGNATURE----- -- gentoo-dev@gentoo.org mailing list
